To all whom imag/"concern:

Beit known thaty ARTHUR G7110-PRINS,

a citizen of the United States, residingat and 4is particularlyadaptedyto beused Vin connectionwith machines for braiding steel wirecables and the like, and is fully de-` scribed in the vfollowingspecification and y shown in the accompanying drawings, V1n

which:y i f j Y Figure 1 -is a side elevation of embodying theinvention; A

Fig. 2 is afront elevation of the same; and

Fig. 3 is a transverse section through the spring for retracting thesheave.

The embodiment illustrated comprises the frame which is integral' with'spindle 11 which is 'adapted to be mounted for rotation upon the tableof a braiding machine not shown. For the purpose of this application,

a carrier it is sufficient to state that as these auto-y matic take-upsare revolved about each other during the braiding operation, the carriermoves alternately toward and from the cen- V ter of the machine towardwhich the wire is fed, thereby necessitating the use of some automaticmeans for taking up the slack in each wire A which is used in thebraiding operation-` e l The wire A is wound upon a reel 12 which isjournalled upon an axle 13 which is carried by a frame 10 and bracket14. The wire Athen passes over the sheave 15 which is journalled on apin 16 and passes down under the movable sheave 17 and thence outthrough the guide 18. Y

The sheave 17 is journalled upon a pin 19 which is carried by abifurcated yoke 20 which is secured to a flexible member 21 which issecured to a cylinder 22 (see Figure 3') which is journalledy upon a pin23. A spiral spring 24 having one end secured to the pin 23 andthe other'end to the inside of the cylinder 22, is so wound as to place theflexible member 21 under tension.v Guides 25 areiplaced on each side ofthe sheave 17 and haverslots 26 adapted to receive the ends of the pins19. Y

At the side of the reel'12 is a brake sheave 27 which isjournalled onthe pin 13 and has alug`28 whichv engages ahole in the end of thereel12; vrIhis sheave is grooved to reccivev abrake band 29'one end of whichis secured to the adjusting screw 30 while the other is 'carriedby theend 31 of the lever 32 which is fulcrumed at 33. This lever is normallyheldin the position shown in the braking position'by means of the spring34. The outer end 35 of the lever 32 is bifurcated vandertends on eachside of the guides 25 so as to engage the outer ends of the pins 19' `asthe sheave 17-is raised by the tension I of theV wire A to the upper endof the slot 26.

F romthe `foregoing, it will be apparent' that when the tension on thewire lifts the sheave 17 against the action of the spring 24, the pin19-will engage the end 35 of the lever 32, thereby momentarily releasingband 29 from the brake sheave 27, thereby permitting the reel 12 to feedthe wire A under the tension of the spring 24 until the sheave 17 hasagain moved down to a point where the shaft 19 is no longer in contactwith the end 35 when the spring 34 will again move the brake lever 32into braking position and the reel 12 will cease feeding until the brakelever 32 is again released.

The tension on the spring 24 may be varied by turning the shoulderedbolt 23 and it may then be locked in adjusted position by means of the`lock-nut 23a.

It will also be noted that the bolt 23 is carried by a frame 36 which isslidable on shown) on the table ofthe machine of which this is a partnormally passes through this depression as the bobbin isV rotated. Ifthe wire A breaks or the bobbin is empty, the frame 36 falls and engagesthe members (not shown) and through mechanism on the table (not shown)causes the braiding machine to stop. v

While I have shown and described certain embodiments of my invention, itis to be understood that it is capable of many modifications. Changestherefore in the construction and arrangement may be made withoutdeparting from the spirit and scope of the invention as disclosed in theappended claims', in which it is myintention to claim all noveltyinherentl inv my invention as broadly 1s/possible in view ofgtliepriorart,
